The chamber includes an inlet port, an outlet port. A downward extension extends into the chamber from the inlet port, and a baffle is disposed at a lower end of the downward extension. A component of the breathing circuit can include a conduit hanging end cap for shipping and storage. The end cap can include a hanging component to allow the breathing circuit component to be hung from a medical stand. The system can detect when breathing circuits are connected in reverse.

The infusion pump for stem cells includes a liquor storage device and an infusion pipe. The inner wall of the liquor storage sac of the liquor storage device and inner walls of the infusion pipe are provided with an anionic protective film to prevent stem cells from adhering to the infusion pump by mutual repulsion between anions. The infusion method includes checking an infusion pump for integrity, losing a liquor stop clamp, injecting a mixed liquor of stem cells and medicine, covering a protective cap, opening the liquor stop clamp, closing the liquor stop clamp for use, connecting an external cone joint with a venous cannula, and then opening the liquor stop clamp. The method also includes steadily placing the liquor storage sac on a horizontal plane using an auxiliary placing device, and after infusion ends, closing the liquor stop clamp, and disconnecting the external cone joint.

A respiratory assembly is provided. The assembly includes a base engaged with at least one connector and in fluid communication with a hose or fluid source for allowing the gaseous flowthrough between the at least one connector, the base and the hose or fluid source. The assembly further includes a pair of sockets engaged with the at least one connector, and a pair of posts, each post selectively engageable with at least one of the pair of sockets. Each post includes a flange that defines an opening therethrough, the openings in fluid communication with each corresponding socket of the pair of sockets. Each post further includes an adhesive adhered to each flange and configured for sealably engaging a patient's nare.

A respiration assistance device includes a nasal respiration assisting section for supplying a gas to the nasal cavity of a living body. The nasal respiration assisting section includes: a first gas supplying portion which supplies a gas below one of the nostrils of the living body; a second gas supplying portion which supplies the gas below the other nostril of the living body; a first tube connecting portion to which a tube for supplying the gas to the first gas supplying portion is connectable; and a second tube connecting portion to which a tube for supplying the gas to the second gas supplying portion is connectable.

A breathing assistance apparatus is configured with features that improve serviceability of the apparatus. The apparatus can include animations to provide instruction regarding correcting easily-identified fault conditions and to provide instruction regarding routine maintenance routines. The apparatus also can be configured with top level control menus that are obscured in a manner to limit manipulation of the top level control elements by unauthorized users.

A patient interface for respiratory therapy includes a nasal interface having nasal prongs configured to contact nares of the user and form a seal. The patient interface also includes a securement portion having a pair of facial pads, each of the facial pads configured to engage the face of a user on opposing sides of the nasal interface. The facial pads are coupled to the bridging portions configured to urge the nasal interface toward the user's face to create or maintain sealing engagement between the nasal interface and the user's face. In some configurations, the securement portion and the nasal interface are detachably coupled to each other.

A nasogastric tube connector device includes an annular connector body for detachably engaging a through hole of a respirator mask having an inner peripheral surface defining a space, and a fixed member having a first concave surface and two side surfaces cooperating with the inner peripheral surface to define an opening of the space for passing of a nasogastric tube therethrough. A first plug member is detachably inserted through the opening into the space, and includes a second concave surface cooperating with the first concave surface to define a main tube hole communicating with the space. A second plug member is detachably inserted into the main tube hole to sealingly close the opening.

Systems, devices, and methods for coupling a tracheostomy tube to a source of humidified breathing gas are disclosed. An adaptor includes a housing, a tracheostomy tube connection device, and a baffle. The housing has an interior surface, an exterior surface, and a breathing gas port. The tracheostomy tube connection device is positioned within the housing and includes an input port for receiving a flow of humidified breathing gas from the breathing gas port and an output port for coupling with the tracheostomy tube. The tracheostomy tube connection device has an internal surface defining a breathing gas passage and an external surface spaced from the interior surface of the housing to create a condensation passage. The baffle may be positioned between the breathing gas port and the input port to cause controlled condensation from the flow of humidified breathing gas by disrupting the flow of humidified breathing gas.

An air conduit for a respiratory therapy device comprises a first end, a second end, and a tube portion, wherein the tube portion comprises a tube wall and an auxiliary structure, such as a rib. The air conduit may deliver a flow of air from a respiratory therapy device or a humidifier to a patient interface. The air conduit may comprise a plurality of auxiliary structures, some of which may consist of a polymeric material, and some of which may comprise a polymeric material and an electrical conductor. An auxiliary structure may be a helical rib extending across a length of the tube portion.

An expandable inter-vivos tube that allows for the use in medical procedures while limiting known complications arising from conventional inter-vivos tubes is presented, wherein the expandable inter-vivos tube comprises a slit formed longitudinally within a tube and a plurality of nipples extending from an outer surface of the tube that are insertable within a corresponding one of a plurality of slides within an outer slidable element that is slidable within the slit. A position of the nipples within the slots causes a distance between the edges of the to increase; thus, increasing a circumference of the inter-vivos tube as the outer element is slide from a proximal end of the tube element to a distal end of the tube.
